Explanation:

The idea of resonance is used to explain bonding in compounds where a single structure does not fully account for all the bonding interactions in a molecule.

A number of equivalent structures are then used to show the nature of bonding in such a molecule. Such structures are called resonance structures or canonical structures. None of these structures individually offer a holistic explanation to the bonding interactions in the molecule under study.

However, a hybrid of all the canonical structures does explain the nature of bonding in the molecule.
